(Sagarra, 1925)
Description:
This butterfly used to be considered a subspecies of the Furry Blue (P. dolus), but there is a clear difference in the number of chromosomes of each species. However, the life cycles and choice of biotope are the same.
Eggs are laid on Sainfoin (Onobrychis viciifolia) and some medicks (Medicago spp.). The caterpillars are frequently attended by ants. This butterfly hibernates when the caterpillar is still small.
It has one generation a year.
Habitat:
Dry calcareous grasslands
